Each of the said guide-members 35 is provided with a slotted portion 36. Extending backwardly from each of said guide-members are partition-members 37, the same being secured at their rear edges to said baelewall 6, and the same being further provided with a cutaway portion 38. Secured to the inner, e de of each side-wall 3 is the hinge-por tion 39 of a movable retainer-member 4:0, the same being provided with a cam-portion tl. Secured to the inner side or" each sidewall 3 is a fiat-spring 4-2, the free end of which engages said movable retainer-member 40 so as to maintain the same in its normal retaining position for the purposes to be herein subsequently described. EX- tending rearwardly from said frame-member 34, and secured thereto in a position adjacent to the said bottom-plate 2, are a pair of supporting rods 43, upon which are supported, behind the said frame-work 34: and its guide-members 35 and between said partition 37, a plurality or advertising placards, cards or signs 14-, the same being provided adjacent to their vertical edges with eyelet-portions 15, which are adapted to register with the slotted portion 36 of said guide-members 35.

Slidably arranged upon each guide-member 35 is a placard or card-shifter 46, the sanie being provided with a slotted portion 47, and suitably secured to said guide-members 35 are retaining shanks 2L3 which extend through the slotted portion 47 of the plac ard-shifter 16, said retaining shanks etS being provided with heads is for securing said placard or card-shifter in operative sliding engagement with said guide-member. The said placard or card-shifter -16 is provided its upper end with a forked portion 50, between the members of which is pivotally mounted upon a pintle 51, a litter-cam 52 which is provided with a nosing 53 and which extends through the slotted portion 36 of said guide-members 35 in position to engage the eyelets or perforated portions 45 of the advertising placard or card 4% next adjacent to said frame-member 34c and its guide-members The said litter-cam 52 is further provided with a lug 5a, which is adapted to be engaged by the free end of a flat spring secured to said placard or card-shifter 46 for the purpose of normally retaining said lifter-cam 52 and its nosing 53 in its operative engagement with said eyelets or perforated portions t5 of the said advertising placards 4A. The lower end 01' said placard-shifter 16 is provided with a rightangled and outwardly extending lug 56 and the said base-plate 2 is provided with a cut-out portion 57 adapted to receive the same. Secured to a pin or lug 58, arranged upon said partition-members 37, is a coiled spring 59, the opposite end or which is secured to a pin or lug 60 arranged upon said placard-shifter 46, the function of said sprin 59 being to maintain and return giid placard-shifter to its nor nialinitial po s ition after the same'has' been operated to shift or lift an advertising placard, card or sign A. Mounted in socket-bearings 61, arranged in the side-walls 3, is a rock-shaft 62, the same extending through a groove or channel 63 in said base-plate 2, and secured upon said rocleshaft 62 are forwardly extending lifting levers which are provided with suitable fingers or similar portions, as 65, adapted to be brought in lifting engagement with the lug of said placard-shifter 46. One of said lifting levers (i -t is provided with an upwardly and baokwardly extending arm 66, and the said base-plate 2 is provided with suitable cutout portions 67 adapted to receive said lifting levers 64. Secured to the inner side of one of said side-walls 3 are a pair of studs 68, and slidably ar-anged upon said studs 68, by means of its slotted portions 69, is a push-bar 70. The said push-bar T0 is provided at its upper end with a eontactpiece 71 adapted to be operatively engaged by said cam-member 32 which is connected with said driving shaft 30. lhe lower end of said push-bar is provided with a similar contact-piece 72 adapted to operatively engagethe free end of said npvn rdly and backwardly extending arm (36 of one of said lifting levers 64:. Secured upon the upper portion of said backwall 6 are a pair of bearing-members 73, and mounted in said bearing members 73 is a rock-shaft T l, one end of which projects through one of the side-walls 3, and has secured upon its outer end a lever-arm 75. Secured upon the inner end of said rock-shaft 74 is a sleeve 76 with which is connected a downwardly extending lever-portion 77. Suitably secured upon the said gearwheel S1 contact-arm 7b, which is adapted to revolve with said gear-wheel, and with every revolution of the wheel 31 is brought in operative engagement with said lever-arm 75. Secured in suitable locations upon said back-wall (5 are a pair of studs 79 upon which are pivotally mounted suitable bearing-portions 80 of oppositely extending swinging lGVQY-ill'l'llS 81., a portion of said swinging lever arms 8]. being doubled upon themselves to form contact-members 82, the free ends of which are adapted to be engaged by said lever-portion 77. Secured to said baclrwall 6 is a flat spring 83, the free end of which is adapted to operatively engage the back of the end-portions of said contact-members 8:2, for the purpose of maintaining and returning said swinging lever-arms to their normal initial positions. Secured upon the free ends of said oppositely extending swinging lever-arms are push-plates 8d.

Having thus described the general construction of my novel advertising device and specified in detail the parts making up the same, it remains to describe, in general, how the said parts cooperate with each other in carrying out the functions of the said novel advertising device. The said advertising device is operated by means of said driving shaft 30, and can be arrangetl so as to be driven by power or hand, to suit the conditions under which the same is to be used. As the said driving shaft 30 revolves, the gear-wheel 31 also revolves, and transmits its revolutions to the respective pinions 13 and 23 by means of which the said two sets of roller-members are revolved in proper di rections. The said driving shaft carries around, during its revolution, the said camlneinber 32, which at a proper time in its revolution engages the contact-piece 71 of said push-bar 70, whereby the latter is forced downwardly, so that its lower contact-piece 72 is brought in engagement with the upwardly and backwardly extending arm 66, whereby the rock-shaft (52 is oscillated so as to carry upward the said leverarnis (i l. The fingers or portions 65 of said lever-arms (ii are thus brought respectively in lifting engagement with the lugs 56 of said placard-shifters Q6. The said placard or card-shifters 46 are thus caused to move upwardly and the nosing of the liftercams 52 are brought in operative contact with the eyelets or perforated port-ions of an advertising placard, card or sign lei, whereby the same is carried upward between the rollern1embers 11 and 17. By the time the said advertising placard llhas been properly engaged by said roller-members 11 and 17, the cani-nien'iber 32 has passed away from its contact with said push-bar TO, and the spring 59 returns the said placard or card-shifter 46, and its operating parts, to their normal initial positions, the nosing 53 of said lifter-cam being swung outwardly and away from contact with the eyelets or perforated portions 45 of said placards 44-, by the downward movement of said placard shifter 1:6. In the meantime, the revolving roller-members 11 and 17 carry said advertising placard, card or sign 4%, upwardly between the same, and force it against the inner side of the sen'ii-circular top or casing t) which guides the placard, card, or sign around until it is forced between the roller-members 2i and 25, which revolving in a direction opposite to the said roller-members 11 and 17, force said placard, card or sign dd downwardly in front of the swinging lever-arms 81 and their push plates 8d, and thereby presents the opposite I or reverse side of said placard or card L4. toward the front of the advertising device. By the time the said placard, card or sign has thus been arranged, the contact-arm 78 is carried around by the gear-wheel 31 and is brought in contact with the levenarm 75, which being pushed downwardly, operates the rock-shaft 74- and its lever-portion T7. The latter is thereby forced against the con- .member 34 and its guide-portions tact-members 82 of the swinging lever-arms 81, whereby the latter are caused to swing inwardly and carry the push-plates 8% against said placard, card or sign e l, forcing the same against the cam-portions ll same back to their normal retaining positions with their free vertical edges engaging the back of said pile or plurality of advertising placards or cards 44, to retain the samein a proper position against the frame- The above described operations are made with each revolution of said gear-wheel 31, so that the advertising placards, cards or signs at are shown at the display opening, successively, and then reversed so that the opposite sides thereof are successively displayed.

I am aware that changes may be made in the several arrangements and combinations of the various devices and parts, as well as in the details of the construction thereof, without departing from the scope of my present. invention, as described in the foregoing specification; and as defined in the claims appended thereto. Hence I do not limit my invention to the exact arrangements and combinations of the devices and parts as described in the said specification, nor do i confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.
